WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 268,125, dated November28, 1882.

Application filed June 3,1882. (No model.) i

To all whom it may concern Be it known that I, GEORGE L. REYNOLDS, ofOakland, county of Alameda, State of California, have inventedImprovements in Window-Screens; and I hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to certain improvements in window-screens of thatclass in which upper and lower wire or other screens or ourtains areattached at one end directly to .the sashes, so that when the latter areraised or lowered to open them the screens or curtains will be extendedover the opening, and thus exclude flies, mosquitoes, and other insectswithout excluding the air.

The invention consists in a means for attaching the screens or curtainsat the top or bottom of the window so that they may be easily detached,a means for keeping the edges of the screens tight, and also the spacebetween the lower bar of the upper sash and the glass of the lower one,and the construction of the screen-weight, which allows it to pass thepulley at the top, and thus have more distance through which to move,which, with the details of construction, will be more fully explained byreference to the accompanying drawings, in which- Figure is a view ofthe window with the lower sash raised, showing the screen and the sidesprings to keep its edge close. Fig. 2 is a view showing both sashespartly open. Fig. 3 is a vertical section taken transversely across thesashes and screens. Fig. 4 is a front view, showing both sashes open andthe balanceweights, cords, and pulleys. Fig. 5 is an enlarged section ofa screen-roller and cord-drum. Fig. 6 is an enlarged view of section ofwindow-sash, frame, screen, and means for forming a tightjoint with thescreen edges. Fig. 7 is transverse section, showing the manner ofincasing the roller. Fig. 8 is a section of weight, showing the mannerof hanging it so that it may pass partly above the pulley. Fig.9 is adetailed view, sh owingthe vertical elastic strip to keep the screentaut. w

A is a window-casing; B and B, the upper and lower sashes, glazed in theusual manner, and G O are screens of any suitable material, having oneedge fixed to the top or bottom of the window-casing and the other edgeto a roller, D, which is fixed to turn upon the top or bottom edge ofthe upper or lower sash-rail, as the case may be. These sash-rails areslightly grooved to partially admit the screenroller, but not so as tocut away too in ueh of the material, and thin metal plates E are securedto the sides of the rail, projecting far enough to inclose the screensand rollers and protect them. Spurs or guides at project just inside theedges of the outer plates, so that the edges of the screens pass betweenthe spurs and the outer plates, E, and are kept in place by them. Theupper and lower edges, respectively, of the screens are made fast tobars F, so that when drawn up to the top in one case and down to thesill in the other they may be fastened there by means of buttons G, andthese hold them so that when the window-sashes are opened the screenswill unroll and close the space above or below the sash. \Vhen it isdesired to leave an open space at these points the buttons are turnedand the screens are allowed to roll up against the sash, thus leavingthe window in its ordinary condition.

The sashes are balanced by a single weight connected with one side by acord passing over a pulley in the usual manner. The weights H H upon theopposite side are connected with drums or spools I, which are secured tothe ends of the rollers, so that as the sashes are moved the screenswill be rolled or unrolled. The cord J, which connects the drum I andweight Hoftheupper sash, winds up as the sash is lowered andnnwinds whenthe sash is pushed up, and this causes the weight to move over doublethe distance necessary. The weight is cutaway with a deep channel on theinside, extending to the bottom, as shown in Fig. 8, and the cord passesdown in a groove which slopes backward from a nearly central point atthe top to a hole, where it passes out at the back near the bottom, andthence it is carried through ahole at 'thebottom and into the channel,where a knot in the end retains it. The weight hung in this manner keepsits upright position as the top inclines toward the cord, and when itarrives at the pulley at the top the channel fits over the pulley, asshown in Fig. 8, while the cord passing over the pulley, as shown in thedotted lines, allows the upper part of the weight to pass above thepulley.

In order to keep the screen edges pressed against the strips between thesashes, so that they will not spring away and leave an opening throughwhich insects may haveingress, I fix one end of thin flat curved springK to the inner side of the strips L, between which and the strip L thewindow-sash moves. When the sash is closed it forces the spring back,straightening them out against the strips to which they are secured; butwhen the sash is opened the free ends of the springs curve forward andpress against the edges of the screens, and thus hold them against thestrips L.

In order to make a tight joint between the netting or screen and thestrips L from the sides opposite to the springs K, I makea groove orslot, M, diagonally in the edge of the strip L and insert a thin stripof rubber or other elastic material, N, so that its edge projects ashort distance. This edge may be straight, wavy, or scalloped, as shown,and when the window is closed the edge rests against the vertical partof the sash. When the window is opened the angle at which the elasticpiece is fixed in the window-strip L causes it to press against thescreen as'it is unrolled, and thus keep a close joint.

I have heretofore described my improved devices as applicable towindow-screens; but it will be manifest that they may also be used withcurtains or an y other flexible fabric where a close joint is desired.

For convenience I have described the screen as fixed to the edges of thesash; but in case the windows are arched at the top the upper one may befixed above the arch in the casing, and the lower edge of the screenhave a curved bar or plate, F, which will just fit the curved top of thewindow, and may be secured to it in the same manner as described forsecuring the straight-ones to the window-sill or top of casingthat is,by buttons G. p

A strip of elastic material, 0, is fixed across the lower rail of theupper sash, and it projects so as to touch the glass of the lower sashand close the opening which would otherwise v be made when the windowsare opened.

Having thus described my invention, what I claim as new, and desire toprotect by Letters Patent, is-

l. In a window-sash, the transverse rail or rails having the rollers Djournaled to them, with screens or curtains attached, as shown, the freeedges of said screens or curtains having plates F fixed to them andadapted to be secured by buttons G, substantially as herein described.

2. In a window, and in combination with the screens or curtains O, theelastic curved strips K, fixed at one end, so that the free end is heldback when the window is closed and springs forward to press against theedge of the screen or curtain when the window is opened, substantiallyas herein described.

3. In a window, and in combination with the screen or curtain G, theelastic strip N, fixed in the vertical strips L of the window so as topress upon the edge of the screen or curtain when the sash is opened,substantially as herein described.

4. In a window, and in combination with a sash having a rolling screenor curtain journaled upon its edge and operated by a balance-weight, theweight H, channeled upon the side next to the pulley,-and having thesuspending-cord J passing down through the channel and secured at thebottom, substantially as herein described.

5. In a window-sash having a screen or curtain roller journaled on thetransverse or meeting rail with the inclosing plates or case E, thespurs or guides a, between which and the outer plate, E, the edges ofthe screen pass and are kept in place, substantially as hereindescribed.

In witness whereof I have hereunto set my hand.
